Benefits of technology
[0004] The present invention is directed to various features of an electrical switch apparatus for a bicycle control device. In one embodiment, an electrical switch apparatus for a bicycle control device comprises a mounting member structured to be mounted to a bicycle, an operating member supported by the mounting member for movement between an operating member start position and an operating member operating position, a first piezoelectric element supported by the mounting member, and a first striking member supported by th
Problems solved by technology
When the shift switch is connected to the shift control unit with wiring, it is difficult to run the wiring along the bicycle, and the wiring detracts from the appearance of the bicycle.
However, if a power supply such as a battery is used to operate the wireless transmitter, the battery tends to become exhausted over time.

Embodiment Construction
[0014]FIG. 1 is a side view of a particular embodiment of a bicycle 1. Bicycle 1 is a mountain bicycle that comprises a frame body 2 constructed by welding together tubing having different cross-sections. A front fork 3 is mounted to the front of frame body 2 for rotation around an inclined axis, and a handlebar assembly 4 is mounted to the top of front fork 3. A saddle 18 is mounted to the upper middle part of frame body 2, a drive mechanism 5 is mounted to the lower part of frame body 2, a front wheel 6 is rotatably mounted to the bottom of front fork 3, and a rear wheel 7 having a hub dynamo 10 is rotatably mounted to the rear of frame body 2. Hub dynamo 10 houses an alternating current generator 19 (not shown) for generating electricity through rotation of rear wheel 7. A front transmission 8 including a control device such as a front derailleur 26f is mounted to the lower middle part of frame body 2, and a rear transmission 9 including a control device such as a rear derailleur...

An electrical switch apparatus for a bicycle control device comprises a mounting member structured to be mounted to a bicycle, an operating member supported by the mounting member for movement between an operating member start position and an operating member operating position, a first piezoelectric element supported by the mounting member, and a first striking member supported by the mounting member for movement between a first striking member start position and a first striking member striking position. The first striking member is operatively coupled to the first operating member such that the first striking member moves from the first striking member start position to the first striking member striking position to strike the first piezoelectric element in response to movement of the first operating member from the first operating member start position to the first operating member operating position.
Description
BACKGROUND OF THE INVENTION [0001] The present invention is directed to bicycles and, more particularly, to an electrical switch apparatus for a bicycle control device. [0002] In recent years, bicycles have been equipped with an increasing number of electrically operated devices operated by various electrical switches. For example, Japanese Laid Open Patent No. 2004-159490 discloses an electrically operated bicycle transmission controlled by an electrical shift switch that is connected to a shift control unit by electrical wiring. A shift signal is communicated to the shift control unit in response to operation of the shift switch, and the shift control unit operates the bicycle transmission accordingly. [0003] When the shift switch is connected to the shift control unit with wiring, it is difficult to run the wiring along the bicycle, and the wiring detracts from the appearance of the bicycle. To alleviate such problems, it may be desirable to transmit the shift signal wirelessly f...
